We do understand quite a bit about gravity, thanks to Einstein, who essentially noticed that in the presence of heavy objects the Universe becomes curved, or distorted. Thus, space changes and time changes. Theory of gravity was his main contribution to physics, even though he got his Nobel Prize for the photoeffect (I guess the Nobel Prize committee did not consider gravity useful at the time - he he). It's also the weakest force in nature, so it's difficult to manipulate or even study! There are a lot of things we still don't understand about gravity or other major interactions. Mostly this is related to our limited ability to study and probe those. Sure, we can put theories out of what could happen, but until we can verify their consequences by probing matter, they are just theories. Einstein's theory is a classical theory of gravity, and quite a few consequences of his theory now have been verified (by the way, that was probably the reason he got his prize for the photoeffect, not gravity - it was not verified at the time)
